Class DefaultHashCollectionFactory

java.lang.Object

org.ow2.authzforce.core.pdp.api.DefaultHashCollectionFactory

All Implemented Interfaces:

HashCollectionFactory

public final class DefaultHashCollectionFactory
extends Object
implements HashCollectionFactory

Default implementation of HashCollectionFactory based on Guava and native Java API. Default expected size is same as for Java API native HashMap/HashSet. This implementation does not distinguish mutable from immutable Map, contrary to Koloboke for instance, therefore the returned Map implementation for newMutableMap() and newUpdatableMap() method variants is the same.
